Provided is a technology in which an image accurately representing a distribution of an area where a specific portion of a cell in an image capturing a cell morphology is captured can be stably acquired. In order to provide the technology, an acquisition unit acquires a virtual cell distribution image in which a distribution of an assumed cell area to be assumed that a specific portion of a cell in a cell morphology image capturing a cell morphology is represented by a plurality of cell display elements, and one or more cell display elements of the plurality of cell display elements is depicted according to an operation of a user. An arithmetic unit obtains a characteristic value relevant to characteristics in appearance and characteristics in appearance of corresponding one or more assumed cell areas in the cell morphology image, with respect to each of the one or more cell display elements described above. A correction unit corrects the virtual cell distribution image to generate a cell distribution image by setting a cell display element of which the characteristic value is at least out of an allowable value range or within a prohibition value range to be in a state of being deleted from the virtual cell distribution image or being unadopted, in one or more cell display elements.
